My phone is stuck at the boot logo, and won't fully boot. The boot with the volume down button pressed doesn't work, or even the volume up thing, in order to enter fastboot I need to let it boot up to the logo then run the
Code:
adb reboot-bootloader
command. when i try the
Code:
adb reboot recovery
command, it boots to the oneplus logo, then reboots normally, and I am back to where I was. I cannot flash a new image, because my bootloader is locked, and in order to unlock it, the phone needs to boot up. Is there a way to unlock the bootloader without a full boot? Can I flash without an unlocked bootloader? Is it bricked? please, any feedback would be appreciated.

So you can't boot into fastboot with the power + volume up button combo after shutting the phone down (hold power)? No you can't unlock bootloader without successfully booting into fastboot. No you can't flash without unlocking the bootloader.

I would think it's bricked, it's virtually impossible to brick this device. So it'll turn on when the power button is pressed, but it won't actually boot, right? Nothing at all happens when using the fastboot button combo? A little background info would be good, what lead to this situation?

The button combos do nothing, not even boot the device normally.
So, what happened is this: I was trying to root my phone, I plugged it into a windows 8.1 machine, and I was following a tutorial by C4Etech. It was working fine, until I unlocked the bootloader, after the it was unlocked, my machine could no longer recognize my device. I uninstalled and reinstalled countless drivers multiple times in an attempt make my machine recognize my device, rebooted my phone, my computer., the adb server, and anyhting else I could. Nothing worked. Angry and frustrated, I plugged it into my Linux Mint machine, and it recognized perfectly! because I am a noob, and have never done anything like this before, I began to panic when I saw that my phone wouldn't reboot like they did in the tutorials right after they unlocked the bootloader, so I skipped that part, and continued with the flashing. after flashing, my phone would no longer boot, so I thought I messed up with the unlocking portion because my phone wouldn't reboot after the "fastboot oem unlock" ( because I am a noob, I thought that the unlock was temporary, and that my many reboots of the phone managed to undo it.). thinking the unlock was the culprit to my broken phone, and thought adb must be glitched since it doesn't reboot after "fastboot oem unlock" like it did in the tutorials, like a genius, i typed in "fastboot oem lock" rebooted into fastmode, then typed in "fastboot oem unlock". I was filled with joy when I saw my phone reboot like it did in the tutorials, but my joy began to fade, as the phone was still booting after several minutes. And thats when I died inside, and began posting on many online forums, because google couldn't find anything that matched my situation.
the button combos stopped working after the flash.

Might be worth a try.
Hello, I came to this forums looking to get some help with a device that a friend gave me to fix. He tried to install some sort of custom ROM on his phone (Moto E XT1527), and after installing it, Im not totally sure what did he touch, but now the phone only boots up to a screen saying the following:
AP Fastboot Flash Mode (Secure)

Baseband: Not Available

(There could be some sort of typo on it)
So far I have tried with a tool that suposedly would flash a ROM into the phone without typing any commands, but it failed at some point.
As for unlocking the bootloader, I was abble to obtain the code, yet when I try to unlock it via fastboot, it says that I need the permission to "Allow OEM Unlock", wich I can't grant because of the SO not booting.
Regarding to what my friend did with it, he's not sure, but he think he deleted some sort of file
Im not an expert on this kind of stuff, yet I can follow steps that are given to me to provide any info or to execute a fix, so I would appreciate any kind of help from you to diagnose and solve this problem
Thanks in advance
A little bump

it can be simply solved ....if you are able to boot to fast boot mode
HOW TO BOOT INTO FAST BOOT
First of all, you have to power off your Moto E.
In order to do so, press power button once and then select “power off” or keep pressing the power button for about 15 seconds.
Wait a few seconds until applying the next step.
After powering off your phone, press power button and volume down key at the same time.
Keep pressing these buttons for about 6, or 7 seconds.
Release the keys when the fastboot / bootloader mode is being displayed.
In fastboot use volume up and volume down keys in order to scroll up and down within bootloader menu and press power button in order to select your option.
if it enters fast boot mod unlock boot loaders ....when it says grant permission using volume up or down button
then flash a custom recovery ...make a factory data reset after you flash custom recovery .....
after all above steps flash any custom rom this will fix all your issues ... you can also try to flash stock rom images via fast boot

Hello and thanks for your answer. I have managed to get into fastboot mode, yet I still can't unlock the bootloader. It stills asks me to grant OEM permissions. Is there any way to grant it without booting into the SO?
Greetings all, As the title suggest I have an HTC One A9 unlocked and I am trying to factory reset it after re-locking bootloader. However, Whenever I boot into boot mode and select to reboot into Recovery mode I am greeted with "Failed to boot to recovery mode" With suggestions to press volume up or down to go back into bootmode. Upon resetting my phone I am sent to a data encryption screen where it ask to enter a password to decrypt my data, Now I can enter any number I want and it goes through saying "The password you entered is correct but your data is corrupt." And gives me a button to factory reset my phone, So I press it and it resets my phone and enters bootmode where my only options are; Reboot, Reboot to bootloader, Boot to download mode, reboot to recovery (Which I just covered does not work for me), Power down. I've looked into this problem before coming here and other people with similar problems have no problems entering recovery mode and even have an option to factory reset the phone from the boot loader menu, However I do not have that 'Factory reset' option in my boot loader menu.
I've spent the last two hours looking at various websites and various topics in this forum but cannot find a solution to aid me. I was hoping to be able to just fix this and return to my phones current settings without wiping anything, But at this point I'll be happy to be able to just get past this and will be satisfied with factory wiping the phone and having it be useable, As I'd like to avoid having to buy a new phone it at all possible.
When I go to recovery mode, I get a phone icon with a red symbol in it. Then I'm able to hold power button and tap the vol up button to proceed. If you're fine wiping the phone, have you tried using the .exe rom file from the HTC site? You need HTC sync installed on the PC, and have phone in download mode use it (at least that's what I've had to do). It should, I believe, reflash recovery mode.

The easyest way should: take your matching RUU and flash your device. This solves your problem
Hi,
is it a problem to relock the bootloader ?
What steps do i have to do ?
Greetz
adb devices
Now, you will see a serial number in the command prompt window which indicates that the device is connected.
adb reboot bootloader
As the device booted into Fastboot mode, type the following command to lock the bootloader.
fastboot oem lock
Now, a confirmation pop-up will appear on the device screen. Use the volume buttons to navigate the highlight to “Relock Bootloader” and press the Power button to confirm it.
And after this, what will happen? Especially when you are rooted? Will it wipe all your data and can you start all over again, or will you face errors/issues/bootloops?
Person I wont just relock my bootloader. Your hash records are broken and you won't get working upgrades anymore, it's even the question if you still can oem unlock it again..... Besides this I don't know if, when you will brick your device, the msm tools still work. If you want to go back to stock better use MSMtools directly and go back to stock. https://www.xda-developers.com/how-to-unbrick-oneplus-nord-msmdownloadtool/amp/

Is this a safe method ? I dont want to brick the phone.... because i read a thread,where the relock ends in a bootloop..... THX
Im not test it but i have last week close BL on my O+ 8pro without any problem!
But before you close BL read this:
https://forum.xda-developers.com/on...de-fix-persist-img-loss-finger-print-t4125909
So i make it. And everything works without any problem.
If you have root remove it.
Flash last original firmware!
(so if you use patched boot.img you have now the "original" again!)
Then relock bootloader...
After that i test it with FP,Face Unlock and OTA update!
Everything is fine ...

This 10.5.11.AC01AA version is ok?
Wanting to root the device via magisk, I tried first to unlock the bootloader of my phone but apparently failed.
I started by activating the developer mode, set oem unlocking developer option in the settings then tried adb reboot bootloader : no success, the phone simply rebooted. A fastboot oem unlock just hung out waiting for a device.
I can go into download mode or recovery mode if that may help...
Any idea how to unlock this bootloader ? How can i check it is effectively unlocked ?
Thanks in advance for any help
It's well known that SAMSUNG mobiles don't have the Fastboot feature: there it's the Download mode.
FYI:
Power off your device. Press Volume Up + Volume Down and plug in your device to a PC to boot into download mode
When you enter download mode, Long press Volume Up button to unlock the bootloader.
ok well, let's forget about fastboot command then.
I'll answer myself on the original question, to unlock the bootloader:
switch off the phone
press volume up and volume down key
plugin a usb cable
choose "device unlock" with a long press volume up
after released the key up, choose "unlock" with volume up again
Now I'm looking to enter the download mode which I can't reach anymore. Any idea xXx yYy ?
Answer myself again
Apply the 3 first steps of my previous answer, you'll be in the same unlock screen as before but the first option will be "Continue". Choose it with volume up and you will end up in download mode !
Now I'll try rooting with magisk...
Rooting with magisk 25.2 done by a classical patching of AP from november release: AP_G736BXXU1BVK2_G736BXXU1BVK2_MQB58744363_REV00
It appears that this is the only thread on the entire forum for this phone?
Having just bought one for the removable battery and the dual SIM, I discovered that samsung in their infinite wisdom disabled the multiple users feature in their oneUI ROM, which really sucks because that was part of the reason I wanted the phone, to segregate certain apps into their own user account.
This all made me realize Root + custom ROM is probably the only way I will ever get that basic functionality returned.
So here I see that rooting is doable, but there appears to be zero results for un-samsung'd ROMs.
Which market is G736B? I was looking at ordering but I am in the US and the Samsung site is giving me the SM-G736UZKEXAA. Would the classical patching work on that?
The G736B model is sparsely distributed in EU, Asia, Africa and Oceania (see here). Your G736W US model is also based on Snapdragon 778G, it is probably the same phone with a few subtleties concerning 5G support (if any, can't find out) and software bloatware. I'd be surprised the above patching doesn't work but ... it's only a guess !
